The free plugin works fine as it can be tested in the live demo https://demo.videosharevod.com/ .
Also repository lists hundreds of active installs meaning many can use it successfully.
As listed in plugin description and on site, video management features require specific hosting options (like FFMPEG) that are 100% hosting related and can only be configured/supported by hosting provider.
Webmasters that have compatible hosting or experienced hosting support can set it up based on instructions:

High number of active installs proves this is not an impossible or highly obfuscated task.
While plugin is free, work of developers and technicians is not.
So installations and specific site troubleshooting can only be provided as or part of paid services.
Installation is included with fully compatible turnkey hosting options that start from $20/month : https://videosharevod.com/hosting/ .
Rating a plugin that is fully functional as junk/worthless/garbage, only because reviewer did not receive paid services for free says more about reviewer than about plugin.
